Intel® Parallel Composer

Exception when run project at debug mode using cilk_for

Dear all,

I have used cilk_plus to make parallel processing into my source code with visual studio 2008 IDE.

But when I build it at debug mode, the project throw an exception below:

"Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function pointer declared with a different calling convention"

How can  I resolve it to make debug mode operated ?

Thanks of all,

Tam Nguyen

 

Cilk Tools error while loading shared libraries

I have successfully compiled cilkplus for gcc (4.8 branch) on Ubuntu 14.04 LTS and compiled the example program fib on the cilkplus website.  I would like to run cilkview and cilkscreen on it, and so I downloaded cilk tools from the website as well.  However, when I try to run cilkview, I get the following error:

Cilkview: Generating scalability data
-t: error while loading shared libraries: -t: cannot open shared object file: No such file or directory

Internal compiler error 010101_239

Hi guys,

I condensed our project down to a piece of code that lets you reproduce the following issue.
When I compile this in Release configuration (Debug works), I get this compiler error:

1>------ Build started: Project: ng-gtest, Configuration: Release x64 ------
1> CilkTest.cpp
1>" : error : 010101_239

Efficient prefix scan library in Cilk Plus and accessible from C?

Is there any efficient prefix scan library for Cilk Plus accessible from C?

I was not able to find any and my implementation can hardly compete with the sequential version :-)

An interface similar to the reducers will work nicely.

Thank you.

Cilk worker scheduling

Hello,

I would like to understand better how Cilk scheduling works. 
I am not sure how to phrase this question so I give it my best.

I have downloaded the latest Intel Cilk runtime release (cilkplus-rtl-003365 -  released 3-May-2013).
I use the classical Fibonacci example in Cilk.

How to Start VTune Amplifier from Ubuntu Launcher

Under Linux many commands are executed from the command line, which is OK. But if the program you are starting has a mouse driven GUI in my view the command line doesn't really make sense.

NOTE: In all the following <install dir> means where you installed Intel® System Studio. On my system this is /opt/intel/system_studio_2014.0.025. Use the location you chose during installation.

VTune Amplifier is for me such a case. To start it from the command line you need to
